TPMS Ranges

[firefighter_2000]

Can anyone tell me what the psi ranges are for the TPMS on heavy load and light load settings? I have searched the owners manual as well as the messages here and cannot come up with a clear answer as to what the ranges are.

Thanks

I believe this is posted on the driver's side door or the B-Pillar on the driver side. This is where it is posted on my 08 Ram and my wife's 2011 car. The high tire pressure is 70 or 80 PSI depending on tire that you are using and I do not believe that the TPMS measure over inflated pressures. I would go no more than the maximum cold air inflation pressure of the tires listed on the side wall.

For the lowest tire pressure this is usually the air inflation pressure on the placard but I have found that I cannot run at this inflation pressure. I need to run 5 PSI higher than the 45 PSI listed on the placard.

Firefighter, I'm not sure which system you have nor am I familiar with the programming/terminology that you have questions about, (heavy load versus light load?). I am using the TST system, running 65 psi on the fifth-wheel camper and the duals on my truck, and 60 psi on the steering front axle. I have the 65 psi axles set at 58 PSI for the low pressure alarm and 101 psi on the high pressure alarm (which is as low as this can be set). The steering axle is set at 54 or 55 and 101 psi.



Hope this helps - Ed

On my 2013 2500, the heavy load pressure is 70 psi and the light load pressure is 45 psi. As Jim W, mentioned those are posted on a sticker on the b pillar inside the driver's door. A few other bits of info, the definition of light load is two passengers weighing 150 lbs each and not more 200 lbs of cargo. Also, the pressures on the sticker are for the stock tires. Now, I don't know about anyone else, but I haven't seen 150 lbs since high school. That's kind of unrealistic in my book. Also, if you decide that you want to run different size tires or even same size tires that run at different pressures, you can take your truck to the dealer and have the TPMS pressures set to what you want. I had that done on mine because I put 285's on it and I got real tired of seeing that warning in the EVIC.

I have the stock TPMS system on my 2013. I usually have the light load turned on. This morning it was alerting me to adjust my pressures, if I wanted light load and it stayed in the heavy load setting.
Just out of the blue.

I reckon I dated myself, and my truck.

Oh, I forgot to mention, the 45 psi light load and the 70 psi heavy load pressures are for the rear tires only. The front pressure is 60 psi for both heavy and light load. The EVIC should show which tires the TPMS thinks are not properly inflated, which will be red on the display. Which tires is it telling you are not properly inflated?

Killgore, don't feel too bad! I had a 2003 before I got my 2013. I had no idea these trucks even had a TPMS till I got my new one.

Thanks, Tim. I'm afraid all this new fangled technology has left me standing beside the road. By the time I can save enough of my allowance to buy one, I'll be too goofy to figure out how to operate it.

I have a 2011 with the blasted TPMS. I like being able to see the actual tire pressures. I hate the alarms. This is another example of the Federal government trying to substitute rules and mandated systems because drivers are stupid and do not check tire pressures or anything much anymore.
